Cognitive Learning Flashcards

1
Q

Learning

A

A process by which knowledge or behaviour changes as a result of experience. It is a relatively permanent change and cannot be attributed to illness, injury, or maturation. It is a result of physical and chemical changes in the brain (changes to chemical aspects of neurotransmission ex. long-term potentiation and changes to structural aspects of neurons ex. more receptor sites or thicker structure increases the sensitivity of post-synaptic dendrites).

Cognitive Revolution

A

1) Insight Learning
—> Koehler (set up puzzles for chimps ex. hanging a banana out of reach).
—> Didn’t get the banana by trial and error, they thought through the problem and came up with a solution.
—> Developed insight (more than learning from reward).
2) Latent Learning
—> Tolman (rats learn mazes without reward. Rats that had the opportunity to go through the maze went through it faster than rats that didn’t get the opportunity when a reward was present).
3) Superstitious Conditioning
—> Believing that x caused y even though there isn’t any association.

Q

Short-Term Memory

A

A storage level of memory where information can be held briefly, from seconds to less than a minute (brief, limited capacity, less detailed, and elaborated concepts). Only the information we pay attention to is committed into short-term memory (STM). This is a fraction of the information in our environment. If not in use, we will forget this information in around 20 to 30 seconds. It is known as working memory and has a limited capacity (we can hold 5 to 9 pieces of information in the mind at one time OR we can hold 3 to 5 pieces of information in the mind at one time).

A vivid memory for an emotionally significant event thought to be permanent and detailed as if frozen in time like a photograph. Extremely vivid memories for emotionally significant events ex. people remembering everything on 911. Frequently recalled.

127
Q

Selective Attention

A

Focus on unusual or arousing details of a crime impairs memory for other details.

128
Q

Weapon Focus

A

Attention is drawn to the weapon at the expense of other information. Unusualness: weapons are unexpected, making them stand out. Emotion/Arousal: more likely to focus on emotional content.

129

When we try to control something mental we are much more likely to fail than if we don’t put in as much effort ex. white bear thinking task.

133
Q

Trying Not To Think About Something Involves

A

1) Intentional (controlled) search for distracters.
2) Automatic monitoring for occurrence of thought.

134
Q

Ironic Effect
